EDWARD C. DAMROW, OF FOND DU LAC, WISCONSIN.

STEAM-JET.

Application filed March V6, 1915.

To all whom 'it may concern Be it known that I, EDWARD C. DAMRow, acitizen of the United States, residing at Fond du Lac, in the county ofFond du Lac and State of lVisconsin, have invented new and usefulImprovements in Steam-Jr ets, of which the following is a specification.

This invention relates to steam jets of the injector type for lifting orelevating liquids.

Devices of this type are at the present time being extensively employedin dairies, creameries, cheese factories and the like for the purpose oflifting and handling liquids. As ordinarily constructed diiliculty isexperi enced in disassembling the parts for the purpose of thoroughlycleaning the same.

The present invention has for its prime object to produce a steam jet,the parts of which may be very conveniently assembled and disassembledfrom each other and from their respective pipe connections, the parts ofthe steam jet being removable so that they may be conveniently cleansedand sterilized.

A further object of the invention is to produce a device of the classdescribed in which the steam inlet and discharge nozzles, as well as thevarious pipe sections, may be readily disassembled and again connectedtogether in a. steam tight manner without the use of skilled labor.

lVith these and other ends in view which will readily appear as thenature of the in vention is better understood, the same con sists in theimproved construction and novel arrangement and combination of partswhich will be hereinafter fully described and particularly pointed outin the claim.

In the accompanyingdrawing has .been illustrated a simple and preferredform of the invention, it being, however, understood that no limitationis necessarily made to the precise structural details therein exhibited,but that changes, alterations and modificar tions within the scope ofthe claim may be resorted to when desired.

In the cli'awing,-Figiiiie 1 is a vertical sectional view of a deviceconstructed in accordance with the invention. Fig. 2 is a verticalsectional view illustrating a slight modification. Fig. 3 is an end viewof one of the connecting sleeves.

Corresponding parts in the several figures are denoted by likecharacters of reference.

The tubular casing of the improved device is substantially T-shapedhaving alining branches 15, 16 and a divergent branch 17,

each of said branches being terminally enlarged and externally threaded,as seen at 18, for the reception of a nut or sleeve 19 having' anannular flange 20 at its outer end. Each of the branches 15, 16 and 17is internally ground at its outer end to form a beveled seat 21.

Therrsteam inlet nozzle 22, the discharge nozzle 23 and the inlet pipeor suction pipe 24 are each provided with a beveled seat engagingportion 25 and also with a circumferential shoulder or ollset 26 adaptedto be engaged by the flange 20 of one of the sleeves or nuts 19, whichlatter are thus utilized for the purpose of assembling the parts. Inconnection with the discharge nozzle there has been shown a pipe section27 having an external annular flange 28 abutting upon the shoulder oroffset 26 of said discharge nozzle and interposed between said shoulderand the liange 2() of the nut or sleeve 19.

rlhe branches of the casing are Vof equal diameter so that the parts ofthe device may be interchanged. In Fig. 1 the inlet and dischargenozzles are connected with the alining branches 15, 16 of the casing,the suction pipe being connected with the divergent branch 17. In Fig. 2the suction pipe and the discharge nozzle are connected with the aliningbranches 15, 16, and the steam inlet nozzle is connected with thedivergent branch 17. This arrangement necessitates a specialconstruction of steam nozzle with an angularly disposed discharge port29. This and other modifications may be resorted to without departingfrom the spirit of the invention.

It is evident that by the construction and arrangement or' the parts ofthe device, as herein shown and described, the inlet and dischargenozzles, as well as the suction pipe, may be separated from the casingby simply unscrewing the nuts or sleeves 19, thus enabling said nozzlesand pipe, as well as the casing, to be easily and thoroughly cleansedand sterilized, after which the parts may be quickly reassembled withoutthe use of other tools than an ordinary wrench or spanner for engagementwith which thc sleeves have been shown provided with laterally extendinglugs 30. The beveled seats 25 of the nozzles and the suction pipe areobviously intended to be ground in such manner as to snugly engage theseats 21 formed on the branches of the casing. thus producing steam andliquid-proof joints.

While the invention has been described as a steain jet7 it is obviousthat other l'luid, such as compressed air, may be utilized :for thepurpose of creating the partial vacuuin required to lift the niillz orother fluid that is to be handled.

Having thus described the invention what is claimed as new, is

A device of the injector type for lifting liquids, the saine consistingof a three-way casing having angularly disposed branches of equaldianieter, each branch being externally threaded and provided with aninternally disposed beveled seat; an inlet nozzle, a discharge nozzleand a suction pipe. each externally beveled to engage one o1 the seatsiand the inlet nozzle and the suction pipe being also each provided withan external shoulder or offset; a discharge pipe section having anexternal llange abutting on the shoulder of the discharge nozzle; andinternally threaded sleeves engaging the branches of the casing andhaving flanges engaging the shoulders or offsets of the inlet nozzle andthe discharge nozzle and the lange of the discharge pipe which is seatedon the offset ot' the discharge nozzle, Whereby the said inlet nozzle,the discharge nozzle and the suction and discharge pipes will bedetacliably and interchangeably connected with the branches of thecasing.

In testimony whereof l ailix in y signature in presence of twowitnesses.
